Oxygen-18 tracer diffusion in nearly stoichiometric single crystalline lithium niobate

Oxygen-18 tracer transport measurements were performed in nearly stoichiometric lithium niobate. To produce such crystals the vapour transport equilibration (VTE) technique was applied using a much larger mass of a lithium-rich two-phase mixture. To avoid Li 2O loss the samples were also held in clo...
